VACUUM SUPPORTING DEVICE.

Specification of Letters Patent.

Application filed April 5, 1910.

Patented Dec. 2'21. 3W6.

Serial No. 553,676.

The invention contemplates providing the usual cup with auxiliary meanswhich automatically and constantly exert a pressure against the scalingedge. to hold the same in contact with a surface, said means being alsoadapted for suspending or siq'iporting articles.

in carrying out the objects oi the invention generally stated a hove itwill be understood, of course, that the essential features thereof arencpazssarily susceptible of changes in details and structuralarrangements, one preferred and practical embodiment of which is shownin the :uzconipanying drawings, wherein Figure l is a top plan View ofthe in) proved vacuum supporter. Fi 2 is a Sec tional View taken on theline" A A, Fig. 1. Fig. 3 is a view in elevation. of the supporter.

Referring to said tltitiilllli'lillhVlilg drawings by numerals, ldesignates a fiatsurlace to which the cup is attache Said cup ispreferably or rubber and provided with a head 3 and. the fiat. sealingedge 4. A sup porting arm. 5 is embedded in head 3 and its ends beyondopposite p tions of said head. 1 Tiaidnrm is preferably olt spring metaland is preferably provided with a hook 6 from \'vhich. articles may besuspended, the other end of said arm terminating in a spiral spring 7.From spring 7, the length of material from which said arm and springsare formed'is bent to form a circular loop 8 \vhich'is of substantiallythe same diameter as the scaling edge 4 of cup 2, said loopheing seated.upon edge 4; and held there by the tension of spring i.

In use, the cup is attached to surface l in the usual manner and whenattached, it will be seen that spring 7 causes arm :3-t'o exert alifting pressure on head 3 and loop 8 to exert a pressure on sealingedge 1; tend; .ing to flatten the same against the surface to which thecup is attached.

Vhat I claim as my invention is I 1. In a device of the characterdescribed, the combination with a vacuum cup, of resilient means :arriedthereby and exerting a urcssure on the edge thereof to hold said cup incontact with a su iporting surface.

2. In a device of the character descrined the combination with a vacuumcup provided with a head and with a. sealing edge, of a supporting armcarried liy said head, a loop seated on said edge, and a springconnecting said arm and loop mnd exerting a pressure tending to forcesaid arm and loop in opposite directions. q I I 3. As a new article )i1non1' "'acti'ii'c. a vacuum cup provideu with head and a scaling edge,a supporting arm carried by said head, a loopseatcd on said edge, and aspring connecting said arm and loo said arm. spring nd ioop torincfl ofa single length t1'csiiiei1t nict al.
